The invention relates to a method for mounting measuring devices and / or communication on a cable transport or distribution of electrical energy particularly medium voltage and an accessory implementation of this method.
Il est connu d'intégrer des dispositifs de contrôle ou de mesure dans l'enveloppe isolante d'un connecteur de câble de transport d'énergie électrique comme décrit par exemple dans le document de brevet US 4 904 932.  It is known to integrate control or measurement devices in the insulating envelope of an electrical energy cable connector as described for example in US Pat. No. 4,904,932.
Ce type d'agencement nécessite la fabrication de connecteurs spécifiques et surtout nécessite de prévoir lors du montage de ce connecteur la mise en place du dispositif de contrôle. En particulier, sur les câbles déjà installés, il est nécessaire de changer tout le connecteur pour équiper ces câbles d'un dispositif de contrôle.  This type of arrangement requires the manufacture of specific connectors and above all requires to provide during the assembly of this connector setting up the control device. In particular, on cables already installed, it is necessary to change the entire connector to equip these cables with a control device.
L'invention résout ce problème en proposant un procédé de montage de dispositifs de mesure et/ou de communication, tels qu'un capteur de courant, un capteur de tension, un coupleur CPL (« Courants Porteurs en Ligne ») et/ou un dispositif d'alimentation en basse tension pour dispositifs électronique de communication par exemple pour le télé-relevé de compteurs d'électricité, sur un câble de transport d'énergie électrique en particulier moyenne tension, qui permette un équipement aisé de câbles déjà installés ou de nouveaux câbles.  The invention solves this problem by proposing a method for mounting measurement and / or communication devices, such as a current sensor, a voltage sensor, a CPL coupler ("Online Carrier Currents") and / or a low-voltage power supply device for electronic communication devices, for example for the remote reading of electricity meters, on a cable for transporting electrical energy, in particular medium voltage, which allows easy equipment of already installed cables or new cables.
Pour ce faire, l'invention propose un procédé de montage d'au moins un dispositif de mesure et/ou de communication sur un câble de transport d'énergie électrique à proximité d'une extrémité de ce câble pourvu d'un équipement de terminaison ou de connexion, caractérisé en ce qu'il consiste à monter un accessoire standard en matière isolante support de ce dispositif de mesure et/ou de communication sur ladite extrémité de câble en amont dudit équipement.

Le mot standard est ici à considérer dans le sens d'universel, c'est-à-dire qu'un accessoire identique est utilisé quels que soient le câble et l'équipement de terminaison ou de connexion.  The standard word is here to be considered in the sense of universal, that is to say that an identical accessory is used regardless of the cable and equipment termination or connection.
Outre l'avantage de la standardisation de l'accessoire utilisé, un tel procédé peut s'appliquer tout autant sur les câbles déjà installés que sur des câbles en cours d'installation et permet d'obtenir un agencement particulièrement compact et de montage aisé et rapide.  In addition to the advantage of the standardization of the accessory used, such a method can be applied just as much to the cables already installed as to the cables being installed and makes it possible to obtain a particularly compact arrangement and easy assembly. fast.
En plus de l'avantage de pouvoir appliquer le procédé conforme à l'invention sur des câbles déjà installés, il est également aisé d'intervenir sur une extrémité de câble pour démonter l'accessoire et réparer ou changer les dispositifs de mesure et/ou de communication portés par l'accessoire en question.  In addition to the advantage of being able to apply the method according to the invention to cables already installed, it is also easy to intervene on a cable end to disassemble the accessory and repair or change the measuring devices and / or communication carried by the accessory in question.
Selon un mode de réalisation préféré de l'invention, ledit accessoire est enfilé sur le conducteur dudit câble dénudé à ladite extrémité.  According to a preferred embodiment of the invention, said accessory is threaded on the conductor of said stripped cable at said end.
Il n'est donc pas nécessaire de couper le conducteur, ce qui réduit la possibilité de défaut électrique et l'agencement est particulièrement compact et de volume réduit.  It is therefore not necessary to cut the conductor, which reduces the possibility of electrical fault and the arrangement is particularly compact and reduced volume.
Avantageusement, ledit accessoire est solidarisé sur ledit conducteur au moyen d'au moins un adaptateur.  Advantageously, said accessory is secured to said conductor by means of at least one adapter.

L'invention est décrite ci-après plus en détail à l'aide de figures représentant uniquement un mode de réalisation préféré de l'invention.  The invention is described below in more detail with the aid of figures representing only a preferred embodiment of the invention.
Les figures 1 et 2 sont des vues en perspective d'une extrémité de câble selon l'invention.  Figures 1 and 2 are perspective views of a cable end according to the invention.
Les figures 3 et 4 sont des vues en perspective et en coupe longitudinale d'un accessoire conforme à l'invention.  Figures 3 and 4 are views in perspective and in longitudinal section of an accessory according to the invention.
La figure 5 est une vue schématique en coupe longitudinale du même accessoire support de capteurs et de coupleurs.  Figure 5 is a schematic longitudinal sectional view of the same support accessory sensors and couplers.
Les figures 6 et 7 sont des vues détaillées en coupe longitudinale du même accessoire support de capteurs et de coupleurs.  Figures 6 and 7 are detailed views in longitudinal section of the same support accessory sensors and couplers.
La figure 8 est une vue détaillée en coupe longitudinale de cet accessoire selon une variante de réalisation.  Figure 8 is a detailed longitudinal sectional view of this accessory according to an alternative embodiment.
La figure 9 est une vue en perspective de détail de la figure 8. Figure 9 is a detail perspective view of Figure 8.
La figure 1 représente une extrémité de câble montée sur un connecteur 1 en L destiné à être connecté à un appareillage servant d'interface de connexion. La figure 2 représente une connexion dans l'air pourvue d'un isolateur à ailettes 2. FIG. 1 represents a cable end mounted on an L-shaped connector 1 intended to be connected to an apparatus serving as a connection interface. FIG. 2 represents an air connection provided with a finned insulator 2.
De façon générale, l'invention s'applique à toute extrémité de câble de transport d'énergie électrique C pourvue d'un équipement de terminaison ou de connexion, par exemple un connecteur 1 ou un isolateur 2.  In general, the invention applies to any end of the electrical energy transport cable C provided with a termination or connection equipment, for example a connector 1 or an insulator 2.
Elle concerne un procédé de montage d'au moins un dispositif de mesure et/ou de communication sur le câble de transport d'énergie électrique C à proximité d'une extrémité de ce câble pourvu de cet équipement de terminaison ou de connexion, consistant à monter un accessoire standard 3 en matière isolante support de ce dispositif de mesure et/ou de communication sur l'extrémité de câble en amont de l'équipement. It relates to a method for mounting at least one measuring and / or communication device on the power transmission cable electrical C near an end of this cable provided with this termination or connection equipment, consisting of mounting a standard accessory 3 insulating material support of the measuring device and / or communication on the cable end upstream equipment.
Un tel procédé peut s'appliquer tout autant sur les câbles déjà installés que sur des câbles en cours d'installation. Dans le premier cas, il suffit de démonter l'équipement 1, 2, de supprimer un tronçon de gaine isolante et de couche semi-conductrice sur l'extrémité de câble, sur une longueur correspondante à celle de l'accessoire, d'enfiler l'accessoire sur le conducteur du câble, pourvu de sa couche isolante, et de remonter l'équipement 1, 2 ou un équipement équivalent neuf.  Such a method can be applied as much on the cables already installed as on cables being installed. In the first case, it suffices to disassemble the equipment 1, 2, to remove a section of insulating sheath and semiconductor layer on the end of the cable, to a length corresponding to that of the accessory, to put on the accessory on the cable conductor, provided with its insulating layer, and reassemble the equipment 1, 2 or equivalent new equipment.
Standard, l'accessoire 3, avantageusement en éthylène- propylène-diène monomère ou en silicone, présente un orifice de diamètre standardisé par lequel il est enfilé sur le câble. Il est donc associé à un agencement d'adaptation constitué de deux adaptateurs 4A, 4B en matière isolante et avantageusement en éthylène-propylène- diène monomère ou en silicone, et solidarisé sur la couche isolante du conducteur au moyen de ces adaptateurs.  Standard, the accessory 3, advantageously ethylene-propylene-diene monomer or silicone, has a standardized diameter orifice through which it is threaded on the cable. It is therefore associated with an adaptation arrangement consisting of two adapters 4A, 4B of insulating material and preferably ethylene-propylene-diene monomer or silicone, and secured to the insulating layer of the conductor by means of these adapters.
Un mode de réalisation de l'accessoire 3 est représenté plus en détail sur les figures 3 et 4.  An embodiment of the accessory 3 is shown in more detail in FIGS. 3 and 4.
Il comporte un premier cylindre creux 3A1, 3A2 et un second cylindre creux 3B1, 3B2 d'axe longitudinal sensiblement perpendiculaire à l'axe longitudinal du premier cylindre creux 3A1, 3A2, l'accessoire étant en forme générale de croix à quatre branches 3A1, 3A2, 3B1, 3B2.  It comprises a first hollow cylinder 3A1, 3A2 and a second hollow cylinder 3B1, 3B2 with a longitudinal axis substantially perpendicular to the longitudinal axis of the first hollow cylinder 3A1, 3A2, the accessory being in the general form of a cross with four branches 3A1, 3A2, 3B1, 3B2.
Essentiellement en matière isolante, avantageusement en éthylène-propylène-diène monomère ou en silicone, l'accessoire 3 est revêtu d'une couche de semi-conducteur 3C et comporte un élément de contrôle de champ 3D intérieur également en matière semi-conductrice. A titre d'exemple, il peut présenter une hauteur h et une largeurEssentially made of insulating material, advantageously ethylene-propylene-diene monomer or silicone, the accessory 3 is coated with a semiconductor layer 3C and has an internal 3D field control element also made of semiconductor material. For example, it may have a height h and a width
1 de l'ordre de 20 à 30 cm. 1 of the order of 20 to 30 cm.
L'invention concerne également l'utilisation d'un tel accessoire 3 tel qu'illustré sur la figure 5 schématique, où le conducteur pourvu de sa couche isolante 6 est représenté schématiquement et les adaptateurs 4A, 4B ne sont pas représentés.  The invention also relates to the use of such an accessory 3 as shown in Figure 5 schematic, wherein the conductor provided with its insulating layer 6 is shown schematically and the adapters 4A, 4B are not shown.
Un capteur de tension CT est monté dans une branche 3B1, un capteur de courant CC est monté sur une branche 3A1 et un coupleur CPL est monté dans une branche 3B2. Cette dernière branche 3B2 porte également le système électronique de mesure SE auquel les capteurs CT, CC et le coupleur CPL sont connectés.  A voltage sensor CT is mounted in a branch 3B1, a DC current sensor is mounted on a branch 3A1 and a coupler CPL is mounted in a branch 3B2. The latter branch 3B2 also carries the electronic measurement system SE to which the CT, DC sensors and the CPL coupler are connected.
Un dispositif d'alimentation en basse tension pour dispositifs électronique de communication par exemple pour le télé-relevé de compteurs d'électricité peut également être monté sur l'accessoire.  A low-voltage supply device for electronic communication devices, for example for the remote reading of electricity meters can also be mounted on the accessory.
L'accessoire décrit ci-dessus est un mode de réalisation préféré permettant le montage de tous ces capteurs, coupleur et système électronique.  The accessory described above is a preferred embodiment for mounting all these sensors, coupler and electronic system.
Cependant, toujours dans le cadre de l'invention, l'accessoire peut ne comporter qu'un seul tronçon de cylindre latéral 3B1 ou 3B2 assurant par exemple le montage de deux capteurs, ou comporter plus de deux tronçons de cylindre latéraux pour le montage d'une pluralité de dispositifs de mesure et/ou de communication.  However, still in the context of the invention, the accessory may have only one side cylinder section 3B1 or 3B2 ensuring for example the mounting of two sensors, or have more than two lateral cylinder sections for mounting a plurality of measurement and / or communication devices.
L'accessoire peut être monté juste en amont de l'équipement 1, The accessory can be mounted just upstream of the equipment 1,
2 , comme représenté sur les figures 1, 2 et 6, mais il peut également être monté à une distance D par exemple de l'ordre de 3 mètres de l'extrémité de câble, comme illustré sur la figure 7, le câble pouvant être reconstruit entre l'accessoire et l'extrémité de câble. 2, as shown in Figures 1, 2 and 6, but it can also be mounted at a distance D for example of the order of 3 meters from the cable end, as shown in Figure 7, the cable can be rebuilt between the accessory and the cable end.
Sur les figures 6 et 7, un capteur de tension CT est monté dans une branche latérale 3B1 et un coupleur CPL est monté dans une autre branche latérale 3B2. Cette dernière branche 3B2 porte également le système électronique de mesure SE auquel le capteur CT et le coupleur CPL sont connectés. In FIGS. 6 and 7, a voltage sensor CT is mounted in a side branch 3B1 and a coupler CPL is mounted in another side branch 3B2. This last branch 3B2 also bears the SE electronic measuring system to which the CT sensor and the PLC coupler are connected.
L'accessoire est traversé par le câble 6 dénudé de sa gaine 6G et de sa couche semi-conductrice 6SC et donc constitué du conducteur pourvu de sa couche isolante. Pour ce faire, le conducteur pourvu de sa couche isolante 6 est enfilé dans les branches inférieures 3A2 et supérieure 3A1 de l'accessoire 3. Une bague de contact métallique 7 entoure le conducteur pourvu de sa couche isolante 6 et assure le passage de pièces de contact traversantes connectant le capteur de tension CT et le coupleur CPL avec le conducteur interne du câble 6.  The accessory is traversed by the cable 6 stripped of its sheath 6G and its semiconductor layer 6SC and thus consists of the conductor provided with its insulating layer. To do this, the conductor provided with its insulating layer 6 is threaded into the lower branches 3A2 and upper 3A1 of the accessory 3. A metal contact ring 7 surrounds the conductor provided with its insulating layer 6 and ensures the passage of pieces of through contacts connecting the CT voltage sensor and the CPL coupler with the inner conductor of the cable 6.
Un adaptateur inférieur 4A solidarise l'accessoire sur le conducteur pourvu de sa couche isolante 6 et est monté sur le câble dans la branche inférieure 3A2 de l'accessoire et est constitué d'un manchon de type réducteur déformable, en soi connu pour le montage de connexions.  A lower adapter 4A secures the accessory to the conductor provided with its insulating layer 6 and is mounted on the cable in the lower branch 3A2 of the accessory and consists of a sleeve of deformable reduction type, known per se for mounting of connections.
Selon la figure 6, l'accessoire est monté juste en amont de l'équipement de terminaison et sa branche supérieure 3A1 porte directement l'enveloppe isolante à ailettes 2.  According to FIG. 6, the accessory is mounted just upstream of the termination equipment and its upper branch 3A1 bears directly the insulating jacket 2.
Selon la figure 7, l'accessoire est monté à une certaine distance D de l'extrémité de câble, comme illustré sur la figure 7 et le câble est reconstruit sur cette distance avec sa couche semi-conductrice 6SC et sa gaine 6G.  According to FIG. 7, the accessory is mounted at a certain distance D from the cable end, as illustrated in FIG. 7, and the cable is reconstructed over this distance with its semiconductor layer 6SC and its sheath 6G.
Dans ce cas, un adaptateur supérieur 4B de préférence de même type que l'adaptateur inférieur 4A est monté sur le câble dans la branche supérieure 3A1 de l'accessoire.  In this case, an upper adapter 4B preferably of the same type as the lower adapter 4A is mounted on the cable in the upper branch 3A1 of the accessory.
Les figures 8 et 9 illustrent une variante de réalisation du coupleur CPL, pouvant être appliqué aux modes de montage représentés sur les figures 6 et 7.  Figures 8 and 9 illustrate an alternative embodiment of the coupler CPL, which can be applied to the mounting modes shown in Figures 6 and 7.
Au lieu de plusieurs condensateurs plats montés en série, ce coupleur CPL comporte ici un seul condensateur 10 en céramique de forme courbe alliant un poids réduit, une capacitance augmentée et une bonne résistance diélectrique. Ses deux faces frontales 10A, 10B de section transversale circulaire sont métallisées, l'une 10 A du côté de la moyenne tension et l'autre 10B du côté de la basse tension. Instead of several flat capacitors connected in series, this coupler CPL here comprises a single capacitor 10 made of ceramic. Curved shape combining reduced weight, increased capacitance and good dielectric strength. Its two end faces 10A, 10B of circular cross section are metallized, one 10A on the medium voltage side and the other 10B on the low voltage side.
Cette forme courbe permet de minimiser la couche isolante nécessaire et donc de gagner de la place pour l'installation du condensateur 10. En effet, seule une partie conique 10C isolante est nécessaire, la branche 3B2' correspondante de l'accessoire 3 étant alors formée de cette partie conique 10C revêtue et prolongée par une gaine semi-conductrice 3C, la surface inclinée interne de cette partie conique 10C recevant la face latérale 10D du condensateur 10.  This curved shape makes it possible to minimize the necessary insulating layer and thus to save space for the installation of the capacitor 10. Indeed, only a conical 10C insulating part is necessary, the corresponding branch 3B2 'of the accessory 3 then being formed. of this conical portion 10C coated and extended by a semiconductor sheath 3C, the inner inclined surface of this conical portion 10C receiving the side face 10D of the capacitor 10.
